Install a Programmable Thermostat

If your home is one of the millions in America that still has an old-fashioned dial thermostat, it’s time to switch. Programmable thermostats allow you to automatically vary the temperature in your home throughout the day. They're easy to install and relatively affordable. To experience the joy of waking up to a warm bedroom while still saving money on your heating bill, all you need is a screwdriver, drill, and (possibly) touch-up paint.
